Recently, NSFOCUS CERT detected that Apache officially released a security bulletin and fixed a command injection vulnerability (CVE-2022-33891) in Apache Spark. Since the Apache Spark UI enables acl through the configuration option Spark.acl.enable, by using an authentication filter, it is possible to check if a user has access to view or modify the application. When the acl configuration is enabled, the code in the HttpSecurityFilter will allow some users to provide arbitrary usernames for impersonation. Attackers can use this function to construct Unix shell command requests to execute arbitrary shell commands. At present, the vulnerability EXP has been made public, and it has been detected that it is being exploited in the wild. Please take measures accordingly.
Apache Spark is a distributed open source processing system for big data workloads. It uses in-memory caching and optimized query execution for fast analytical queries on data of any size. It provides development APIs in Java, Scala, Python, and R, enabling code reuse across multiple workloads—batch processing, interactive querying, real-time analytics, machine learning, and graph processing, etc.
